For Battery Monitor Widget, default battery logging is performed every 10 minutes by default, however on MIUI ROMs it turns into 50 minutes and there's no way to work-around this without impacting battery severely and risking other users with non-MIUI ROMs be affected.

For Android Tuner, you may optionally set app to update and log mA data every minute, which on MIUI Roms will turn into an update and logging every 5 minutes instead.
